Description
Technical field
The invention belongs to polycarboxylate water-reducer field, more particularly to a kind of ultra high early strength poly-carboxylic water reducer and its preparation side
Method.
Background technology
In recent years, the research of concrete admixture has tended to develop towards high-performance, pollution-free direction with production, concrete
Water reducer is that application surface is most wide in concrete admixture, the maximum one kind of usage amount., can in water reducer incorporation fresh concrete
The flocculent structure of cement granules is destroyed, plays a part of disperse cement particles and hydrated cementitious particle, so as to discharge flocculation knot
Free water in structure, increase the mobility of concrete mix.PCEs water reducers belong to anionic surfactant, mix water
In slurry body, adsorb in the cement particle surface with cation, and be dissociated into hydrophilic and oleophilic function organic anion base
Group.
Water reducer molecular skeleton is made up of main chain and more side chain.Contain more active group, and polarity on main chain
Relatively strong, by these active groups, main chain " can be anchored " on cement particle surface, and side chain has hydrophily, Ke Yishen
Exhibition in the liquid phase, so as to form larger three-dimensional adsorption structure in cement particle surface, produces space steric effect, so that water
Mud particle is scattered and stably.Carboxylic acid ion makes the negative electrical charge on cement granules band produce Coulomb repulsion work between cement granules
With, and disperse cement granules, contact of the increase cement granules with water, make the abundant aquation of cement.In the mistake of disperse cement particles
Cheng Zhong, the Free water that agglomerate is included is discharged, workability is improved, reduces and mix water.
Polycarboxylate water-reducer (PCEs) with combed molecular structure generally by polyethoxy (PEO) side chain graft to it is cloudy from
Formed on the main chain of son, PEO side chains produce space steric effect between the cement granules for being suspended in aqueous phase, by adjusting PCEs
Molecular structure, different purposes can be reached, as slump retaining is good, water-reducing rate is high, and cohesiveness is good, and resistance to mud is good etc., in addition low
Cost, it is pollution-free the advantages that, polycarboxylate water-reducer research turn into domestic and international concrete admixture research and development focus.
The primary raw material of poly carboxylic acid series water reducer has unsaturated acids, such as maleic anhydride, maleic acid and acrylic acid, metering system
Alkenyl material, poly styrene sulfonate or the esters such as the polymerizable carboxylic acid such as acid, polyalkenyl hydrocarbon, ether, alcohol and acrylates, ester,
Benzenediol, acrylamide etc., synthetic method generally have polymerisable monomer to be directly copolymerized, polymerize Post functionalization method, in-situ polymerization
With grafting etc..
Polymerisable monomer is directly copolymerized：This synthetic method usually first prepares the side chain polymeric monomer with polymerization activity
(being usually methoxy polyethylene glycol methacrylate-styrene polymer), then the monomer of certain match ratio is mixed, directly use
Polymerisation in solution and finished product.This polymerization, technique is simple, but on condition that want the polymerizable polymeric monomer of synthesizing activity, and it is big single
The performance of body directly determines and affected the performance of final products polycarboxylate water-reducer.
The surface-active macromonomer that China market is used to produce PCEs water reducers at present mainly has：
MPEG：Poly glycol monomethyl ether
VPEG：4- hydroxy butyl vinyl ether APEOs
APEG：Allyl alcohol polyethenoxy ether
HPEG：Isobutene alcohol APEO
TPEG：Isoamyl alcohol polyoxyethylene ether
APEG is bar-shaped rigid structure, high to cement adsorbance, and TPEG microstructures are star-shape polymers, have flexibility
Segment microstructure is few to cement adsorbance.
APEG is the primary raw material of synthesizing polycarboxylic acid high-performance water reducing agent, and the PCEs water reducers of synthesis have dispersiveness
Well, the advantages that volume is low, and water-reducing rate is high, adaptability is good；Shortcoming is inferior suitability, and Slump Time losing of Large is big.HPEG with
TPEG is the water reducer of raw material production, and water-reducing rate is more or less the same, but summer uses, and slump retaining gap is larger, and cement adaptability is slightly
Difference.Using the polycarboxylate water-reducer that TPEG is main material production, water-reducing rate is high, and slump retaining is good, strong to cement adaptability, production
Process equipment is simple, and by polycarboxylate water-reducer, manufacturer favors.But complexity due to China's concrete raw material and various
Property, especially when the soil content of sandstone is big, the slump-loss of concrete is big, the polycarboxylate water-reducer produced by TPEG,
Because even intercalation occurs for PEG side chains and soil, make its resistance to mud poor, can not meet the requirement of concrete construction performance.
RCOO-With Ca2+Ionization forms complex compound, reduces the Ca in solution2+Concentration, delay Ca (OH)2Form knot
Crystalline substance, the formation of C-H-S gels is reduced, has delayed the aquation of cement.
The content of the invention
The invention provides a kind of ultra high early strength poly-carboxylic water reducer, the water reducer has cation electrodeposition in the molecular structure
Lotus, the water of cement can be promoted and changed to react, accelerate the strength development of maturing, there is super hardening effect, and due to it
Unique both sexes structure and space steric effect so that it has unique cement granules dispersibility, and water-reducing rate is high, resistance to soil
Property is good.
